how to adapt a path name to the OS

how to adapt a path name to the OS

[evangeli]

Hello
let us assume i have a string S corresponding to a path that has the
following value :
"/home/test/me/test path"

is there a predefined function that can adapt S to my OS. On my example
i'll have
F(S) = "/home/test/me/test\ path"

Thanks

No, not predefined.

What compiler (inc version)/OS are you using?

If you are using Linux and a more recent version of GNAT/gcc then you 
may find that all you really need is in Ada.Directories.

It seems i do not have ada.directories on my system
i have gnat 3.15p

so you may look at GNAT.Directory_Operations (g-dirope.ads)

The quotes are only needed to protect certain characters from the
shell.  So, you need to quote only if you want to pass the string to a
shell.  In the case of bash, I suggest you give up on quoting and
simply enclose the path in single quotes (').

If you want to pass the string to Ada.Text_IO.Open to open a file,
then you don't need quoting at all.

yes it helps
i am using procedure Gnat.Os_Lib.Spawn
before calling it i call Argument_String_To_List on a string that
contains a path with spaces

sorry for bothering you with this stupid mistake
